Variety Description

Varieties used for comparison: 'Van', 'Sumnue' (Cristalina) and 'Santina'

Summary: 'SPC136' is a non-self fertile, sweet cherry variety which has larger flowers with wider petals than the three reference varieties. The fruit and the stone of 'SPC136' are larger than the fruit and stone of 'Van', 'Sumnue' and 'Santina'. 'SPC136' has a less prominent suture than 'Van' and 'Santina' which have a very prominent suture. The fruit stalk of 'SPC136' is longer than any of the reference varieties. 'SPC136' matures very early to early, after 'Santina' and before 'Van'.

Description:

TREE: normal type, medium vigour, upright growth habit, medium crown density
ONE-YEAR OLD SHOOT: no anthoycanin, erect attitude, medium thickness, short to medium internodes, no pubescence, many lenticels, very few or no flower buds
VEGETATIVE BUD: large size, conical to round, adpressed to slightly held out from shoot, medium sized bud support
CURRENT YEAR'S SHOOT: no pubescence, no anthocyanin at tip

LEAF: horizontal to oblique downwards attitude, broad obovate to elliptical shape, acute angle at tip, U-shaped base, acuminate apex, slightly concave in profile, weak to medium pubescence on lower side
UPPER SIDE OF LEAF BLADE: dark green, no anthocyanin colouration, weak glossiness, yellow before leaf fall
LEAF BLADE MARGIN: biserrate, medium depth indentations
PETIOLE: anthocyanin present
NECTARIES: usually three, red colour, kidney shaped

FLOWER: medium flowering density, borne in clusters, single type, white bud
PEDICEL: medium thickness, no pubescence
PETAL: medium to large size, round shape, overlapping margins, light pink colour

PISTIL: normal, no supplementary pistil, no pubescence on ovary

FRUIT: very large, kidney shaped, flattened to rounded in lateral view, largest diameter towards middle, flat to pointed apex
FRUIT SKIN: wine red, few light coloured medium sized dots, low prominence of suture, moderately susceptible to rain-induced cracking
FRUIT JUICE: dark red to black
FRUIT FLESH: dark red to purple, firm, low acidity, medium sweetness, strong juiciness
FRUIT STALK: long, medium thickness
STONE: non-adherent to flesh, large size, medium size relative to fruit, obovate in front view, intermediate in lateral view, round in basal view, symmetrical, strong keel development

PERFORMANCE CHARACTERISTICS: intermediate fruiting precocity, late flowering, not self-fertile, very early to early fruit maturity, medium fruit setting

Origin & Breeding History: 'SPC136' was the result of the cross '2S-36-36' x 'Summit', which was made at the Pacific Agriculture Research Centre, Agriculture and Agri-Food Canada, Summerland, B.C. in 1981. The parent '2C-36-36' was a Summerland breeding line which was not commercially viable and which was later dropped from the breeding programme. The seedling cross was designated 'SPC136' in 1997. Two propagations were made on Prunus avium rootstock and planted out in a trial block at the Summerland Research Centre in 1987. Evaluation of the selection began upon fruiting. The variety 'SPC136' was selected on the basis of maturity date, size of fruit, firmness, field splits, fruit shape, skin and flesh colour, fertility, luster, productivity and precocity.

Tests & Trials: Trials for 'SPC136' were conducted at the Pacific Agriculture Research Centre, Agriculture and Agri-Food Canada, Summerland, British Columbia from 2003 to 2005. The candidate variety and three reference varieties were planted in close proximity in test blocks located in Field 4 and 13. The trials consisted of 4 trees per variety, grafted onto 'Mazzard' rootstock. Measured observations were based on a minimum of 15 measurements.
